FALL RIVER — Aaron Hernandez’s lawyers filed a motion on Tuesday seeking to inspect a computer hard drive that police detectives took from his North Attleborough home while executing a search warrant last summer in the Odin Lloyd murder investigation.

After inspecting a copy of the hard drive, which was connected to the home surveillance system, Hernandez’s lawyers said there are times when some video files “skip without explanation,” so they want to inspect the original hard drive to ensure the copy they have is the same as the original, according to court documents.

In a December 2013 letter to prosecutors, Hernandez’s defense team said its copy appeared to have “some significant gaps during a critical time.” The defense team’s expert wants to see whether those gaps appear on the original hard drive, according to court documents.

Prosecutors agreed to allow the defense team to inspect the hard drive, but Hernandez’s lawyers said the Bristol County District Attorney’s Office IT representative offered only to let them inspect the device’s exterior.

“Only by reviewing the original hard drive and its files, while connected to a computer, can it be determined when alterations to the drive were last made, when the system was disconnected, when it was last accessed, and whether the copy provided to the defense is the same as the original,” defense attorneys Michael K. Fee and James L. Sultan wrote.

Hernandez, 24, the former Patriots tight end, is scheduled to appear on June 16 for a motion hearing in Fall River Superior Court, where he is facing murder and firearm charges stemming from Lloyd’s June 2013 homicide in the North Attleborough Industrial Park. Hernandez will also be arraigned that day on assault and threat charges stemming from allegations he attacked an inmate and threatened a correctional officer at the Bristol County House of Correction in Dartmouth.

Last month, Hernandez pleaded not guilty to charges he murdered two men in a 2012 drive-by shooting in Boston. It is expected that Hernandez, who is being held without bail in Bristol County, will first stand trial for Lloyd’s killing, which prosecutors allege he “orchestrated” along with his two alleged accomplices, Carlos Ortiz and Ernest Wallace.

Prosecutors said Hernandez is shown on his home surveillance system holding what appeared to be a handgun shortly after he, Ortiz and Wallace returned to the home from the industrial park, where Lloyd’s bullet-riddled body was discovered the next morning. Last month, Hernandez’s lawyers filed a motion to dismiss the murder charge on the grounds that the prosecution had not produced evidence to show Hernandez had a motive to kill Lloyd.
